GROUNDWATER CHEMISTRY GRAPHING TOOL
Attached is an Apache Open Office Calc Spreadsheet, “GraphingTool.ods”.
This document creates line graphs and box plots which can be easily adapted according to the user’s needs. Up to four data sets at once may be inputted by the user. This data is plotted automatically and can be compared to a seawater curve (which can be normalised to the chloride in the samples) and to local rainwater data from DEFRA’s UKEAP: Precip-Net. The tool can also be used to produce cumulative frequency plots of concentration data, with the possibility of comparing up to 4 datasets at once.
